Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery swapping equipment technology, specifically relating to a robotic arm battery swapping structure. Background Technology
[0002] New energy vehicles refer to automobiles that use unconventional vehicle fuels as their power source (or use conventional vehicle fuels but employ new onboard power devices), integrating advanced technologies in vehicle power control and drive, resulting in vehicles with advanced technical principles and new technologies and structures. New energy vehicles include: hybrid electric vehicles, pure electric vehicles, fuel cell vehicles, hydrogen engine vehicles, as well as natural gas vehicles, alcohol-ether vehicles, etc.
[0003] Currently, in the process of battery swapping for new energy vehicles, battery swapping stations can only support 2-3 compatible vehicle models if the excavation pits are quite deep. However, once the initial construction is completed, the pit depth cannot be increased later. Therefore, it is impossible to support battery swapping for other chassis-based battery swapping models under limited pit depth and different unlocking / unlocking positions, resulting in low compatibility. Utility Model Content
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A robotic arm battery swapping structure includes a frame body and a wheel clamping unit and a battery pack transport unit mounted on the frame body, and also includes a battery pack lifting unit and a battery pack unlocking unit disposed in the middle of the battery pack transport unit;
[0006] The battery pack transport unit includes at least two transport frames and a first drive element mounted on the transport frames. The output end of the first drive element is connected to a belt drive element. The first drive element can drive the battery pack to move through the belt drive element. The transport frame is fixed to the frame body by a number of legs.
[0007] The battery pack unlocking unit includes at least one set of robotic arms mounted on the frame body and a gun head mounted on the robotic arms for unlocking.
[0008] Furthermore, the wheel clamping unit includes a front wheel side and a rear wheel side. The front wheel side includes a front wheel frame mounted on the frame body and at least two sets of front wheel platforms mounted on the front wheel frame, namely a first front wheel platform and a second front wheel platform. The front wheel frame is also provided with two sets of front wheel centering components, namely a first clamping component and a second clamping component. The first clamping component and the second clamping component move inward / outward simultaneously.
[0009] Furthermore, the front wheel platform consists of two rows of inwardly inclined cylinders, with the angle between the two rows of cylinders being 100 to 150°.
[0010] Furthermore, the front wheel alignment assembly includes a front wheel clamping block that slides on the front wheel frame, the front wheel clamping block being located between two rows of cylinders, and the front wheel frame also having a second drive element and a lead screw, the second drive element being able to drive the front wheel clamping block to slide via the lead screw.
[0011] Furthermore, the rear wheel side includes a rear wheel frame mounted on the frame body and at least two sets of rear wheel platforms disposed on the rear wheel frame, namely a first rear wheel platform and a second rear wheel platform. The rear wheel frame is also provided with two sets of rear wheel alignment components, and the two sets of rear wheel alignment components move inward / outward simultaneously.
[0012] Furthermore, the rear wheel alignment assembly includes a third drive element and a rear wheel clamping block, wherein the third drive element can drive the rear wheel clamping block to slide on the rear wheel carrier.
[0013] Furthermore, the battery pack lifting unit includes a fourth drive element and a scissor fork platform, the fourth drive element being able to drive the scissor fork platform to move up / down.
[0014] The beneficial effects of this utility model are:
[0015] This invention utilizes a robotic arm locking / unlocking mechanism. For different chassis-type battery swapping vehicles, the robotic arm can be driven by a power source to unlock the battery pack via a locking / unlocking gun within its full stroke range. After unlocking, the battery-carrying platform uses a scissor fork to lower the battery, placing it stably on the battery conveyor line. The conveyor line then transports the battery to the battery compartment for storage and charging. When a fully loaded battery is transported to a fixed position on the platform via the battery conveyor line, the battery-carrying platform uses a scissor fork to lift the fully loaded battery upwards, and the robotic arm locks the battery pack within its full stroke range, completing the battery swapping process for the vehicle. This solves the problem of battery swapping for various chassis-type battery swapping vehicles under conditions of limited depth space and different locking / unlocking positions.
